1SDA104777R1 ABB Kit HR/VR FP XT5 400A 4pcs Same Length

Why Choose the ABB Kit HR/VR FP XT5 400A 4pcs Same Length?

The ABB Kit HR/VR FP XT5 400A 4pcs (same length), order code 1SDA104777R1, is a genuine set of rear terminals for the fixed part of ABB SACE Tmax XT5 circuit breakers. Designed for the 400 A XT5 platform, the kit contains four terminals for compatible four-pole installations.

The HR/VR design provides rear terminals that can be arranged in horizontal or vertical orientation, giving panel builders greater flexibility when connecting busbars behind the circuit breaker. This version uses terminals of the same length, helping provide a consistent rear connection geometry across the four poles.

ABB specifies the 1SDA104777R1 for the XT5 400 A fixed part and identifies IEC 60947-2 as the reference standard. The accessory is also listed with IEC and UL certification, making it a versatile manufacturer-engineered connection solution for compatible low-voltage switchboard assemblies.

Flexible Rear Connections for ABB XT5 Fixed Parts

Rear terminal arrangements are useful in switchboards where the main busbars or conductors are positioned behind the circuit breaker. The ABB 1SDA104777R1 provides HR/VR orientable rear terminals, allowing the connection arrangement to be adapted horizontally or vertically to suit the panel layout while retaining an ABB-engineered interface with the XT5 fixed part.

The kit contains four same-length terminals for a four-pole configuration. ABB's XT5 installation documentation identifies this specific accessory for the P/W 400 HR/VR connection arrangement and indicates a mounting torque of 5 Nm, supporting consistent installation when fitted according to the manufacturer's instructions.

Typical Applications

• ABB SACE Tmax XT5 400 A circuit-breaker assemblies.
• Four-pole XT5 fixed parts.
• Rear-connected low-voltage switchboards.
• Horizontal rear busbar arrangements.
• Vertical rear busbar arrangements.
